VENTILATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 699,352, dated May 6,1902.

Application filed August 17, 1901. Serial No. 72,436. (No model.)

To all whom zit may concern.-

Be it known that we, JOHN TITUS, a resident of Oyster Bay, and WILLIAMTITUS, a resident of Old Westbury, in the town of North Hempstead, inthe county of Nassau and State of New York, citizens of the UnitedStates, have invented certain new and useful Improvements in VentilatingApparatus; and we do hereby declare that the following is a full, clear,and exact description of the same, reference being had to theaccompanying drawings, making a part of this specification, in whichFigure 1 is a partial vertical sectional view of a ventilating apparatusmade according to our invention. Fig. 2 is a horizontal sectional viewthereof, taken in the line mm of Fig. 1. Figs. 3 and 4 are detail viewsof devices included in the apparatus.

This invention relates to that class of ventilating apparatuses in whichtwo volumes or streams of air of different temperatures are mingledprior to their access to the room or place to be ventilated.

The object of said invention is to provide simple and effective meansfor automatically regulating and controlling the temperature, volume,and pressure of the commingled air as the same is supplied to said roomor place.

To this end theinvention comprises certain new and useful combinationsof parts hereinafter fully described and specified in the claimsappended hereto.

A is a cooling-chamber or cooler, which may be of any suitableconstruction-as, for example, and as shown on the drawings, an iceboXwith a horizontal diaphragm a, by means of which a circuitous passage isgiven to the air as it passes through to more thoroughly refrigerate thesame. From the cooling-chamber extends upward a vertical cold-air shaft15, and placed in suitable relation with the cooling-chamber is anair-forcing apparatus, preferably, and as shown in the drawings, arotary fan-blower O, which may be driven by a pulley b, and whereof theinlet from the atmosphere or from any desired source of airsupply isshown at c in Fig. 1. This air-forcing apparatus or blower C has twooutlets e and d, which extend from the throat of the blower, as shown inFig. 1. Of these outlets d communicates with the cooler A, while 6communicates with a secondary vertical air shaft or pipe D, which isparallel with the cold-air shaft B, so that in the operation of theblower (J air is simultaneously forced into the secondary air-shaft Ddirect from the blower and into the cooler A and thence into thecold-air shaft B. In the throat e of the blower is provided a swingingvalve E, which acts in conjunction with vents a b at oppo site sides ofsaid throat, as shown in Fig. 1. This valve is so arranged that byadjusting it in one direction or the other the supply of air to the oneshaft or the other may be increased or diminished at will, theair-supply to the one shaft being diminished as that of the other isincreased, and conversely, while by bringing the valve against one orthe other of its vents the supply of air to one or the other, as thecase may be, of saids shafts may be entirely out off. The requiredadjustment may be given to this valve by means of an arm a attached toan outer end of its pivot b and held by a pin 0 which passes through ahole in the arm into any one of several,

corresponding holes in a fixed section d, as shown.

Located between the two air-shafts B and D is a mixing-chamber E, whichat one end communicates with the coldair shaft B and at the other withthe air-shaft D. The'end of this mixing-chamber which communicates withthe shaft B has a register f, preferably of the semirotative kind, forcontrolling the inflow of air from said shaft to said chamber. In likemanner and for like purpose that end of the chamber which communicateswith the secondary shaft D is provided with a register g. Each of theseregisters has a radial arm h, and these arms of the two registers areconnected by a rod 1', so that an impulse or movement given to the oneregister will be transmitted to the other. The registers are so providedthat when one of them opens 5 or enlarges its passages to increase thevolsuitable way-as, for example, by a linkjwith the movable part of asuitable thermostat F, so that changes of temperature acting upon theregisters f and g the relative volumes of air passed into themixing-chamber from the two air-shafts are automatically controlled. Themixing-chamber has an outlet into the room or place to be ventilated.This outlet is shown at k and is provided with a register m, by whichthe outflow of air therefrom may be controlled. The thermostat justhereinbefore mentioned should of course be suitably placed in the roomor place to be ventilated. To the registermof the outlet is of theair-mixing chamber E is provided a projecting tube or nozzle 'n, towhich in any suitable manner is attached a flexible tube'GJ The free endof this flexible tube being open, air may be conducted at will to anypart of the room or place to be ventilated-as, for example, into anydesired relation with a couch, bed, chair, or the like, as may bedesired.

Upon the chamber E and with its lower end communicating with saidchamber is a cylinder H, in which is a longitudinally-movable plunger I,the upper projecting end of which bears against the under side of aloaded lever J. This lever is connected by a link 0" with a crank-arm son the register m of the outlet k of the chamber. When the pressurewithin the chamber exceeds a desired or foredetermined limit,the plungerI is lifted,thereby actuating the lever J to operate said registertomore or less close the same, thereby regulating the volume of the mixedair from the chamber to the room or place to be ventilated andcontrolling the pressure under which it is so admitted to an extentproportioned to the degree to which the air is throttled in its passagethrough said register. Any desired number of mixing-chambers and theirherein-described adjuncts may be employed in connection with the twoair-shafts, according to the number of stories of the structure to beventilated. The two volumes of air, that from the air-shaftD being ofthe higher temperatureas, for example, the normal temperature for thetime being of the outer atmosphere-=while that from the cold air shaftis refrigerated or of lower temperature, meet and commingle in themixing-chamber, and thus reach a temperature common to both beforeissuing from said chamber to the room or place to be ventilated.
